Here, one of hip hop's must under-appreciated producers talks to Chairman Mao (Ego Trip and more) on the role he has played in some of hip hop's most important moments: including the creation of 'Illmatic'; J Dilla; and how on 'MBDTF', Kanye West looked to Tip for help on recreating the Mobb Deep drum feel.
Sidenote: Go back and listen to the drums on 'Midnight Marauders', then listen to 'The Infamous'.

Sidenote: Q-Tip gave Swizz Beats the Justice records that he sampled on 'On To The Next One' for Jay Z.
